Abstract

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket ( 1 ), an insertion block ( 2 ) and pushing and clamping pliers ( 3 ), wherein the ceramic tile leveling bracket ( 1 ) is provided at the junction between two adjacent ceramic tiles ( 4 ), one end of the insertion block ( 2 ) is inserted into an insertion block through hole ( 16 ) of the ceramic tile leveling bracket ( 1 ), and the pushing and clamping pliers ( 3 ) push and clamp the insertion block ( 2 ) into the insertion block through hole ( 16 ), so that an insertion block bottom surface ( 21 ) is tangent to upper surfaces of the two ceramic tiles ( 4 ). The ceramic tile leveling and laying system is easy to operate, and helps to improve the laying efficiency and laying quality.

First claim

The invention claimed is:

1. A ceramic tile leveling bracket, comprising:
a pad for supporting bottom surfaces of two adjacent ceramic tiles;
an insert protruding from a center line of an upper surface of the pad, for being inserted into a gap between the two adjacent ceramic tiles; and
a breakable sheet located at a lower portion of the insert and adjacent to the pad;
wherein the insert comprises:
a hole which penetrates the insert and into which an insertion block is inserted; and
a bayonet disposed on a side edge of the insert on one or either side, and the bayonet having a height from the pad which is greater than a height of the sheet from the pad;
a hook-shaped engagement block disposed on a side edge of the insert on one or either side and the hook-shaped engagement block protruding toward the bayonet;
wherein a bottom of the bayonet is arc-shaped, and a portion of the bayonet that is close to the hook-shaped engagement block forms a hook-shaped bayonet portion.

2. The ceramic tile leveling bracket of claim 1 , wherein the insert comprises:
a linear groove recessed from a surface of the insert on one or either side, a bottom of the linear groove being the sheet.

3. The ceramic tile leveling bracket of claim 1 , wherein a bottom surface of the pad is an arc-shaped surface, which is part of a cylindrical side surface; and
two ends of the pad extend upward from a middle of the bottom surface to make contact with the bottom surfaces of the ceramic tiles.

4. The ceramic tile leveling bracket of claim 1 , wherein the pad comprises:
reinforcing ribs disposed at tops of two ends of the pad; and/or
a pad through hole which penetrates the pad.

5. The ceramic tile leveling bracket of claim 1 , wherein
a longitudinal section of the insertion block is wedge-shaped, which comprises:
an insertion block bottom surface, which is a plane;
an insertion block top surface, which is an inclined plane and forms an acute angle with the insertion block bottom surface; and
two or more serrations protruding from the insertion block top surface and arranged in the same straight line, wherein each serration comprises a vertical serration surface and an inclined serration surface, and the vertical serration surface is perpendicular to the insertion block bottom surface.

6. A ceramic tile leveling and laying system comprising:
a ceramic tile leveling bracket of claim 1 , which is provided at a junction between two adjacent ceramic tiles;
an insertion block having one end inserted into a hole of the ceramic tile leveling bracket; and
pushing and clamping pliers, for pushing and clamping the insertion block to the hole of the ceramic tile leveling bracket such that an insertion block bottom surface is tangent to upper surfaces of the two ceramic tiles.
